Conditions and AssumptionsConditions and Assumptions
- PC- Internet connection- Internet Explorer 5.0 or higher - Netscape 7.0 - Cortona VRML plug-in for IE
![Page 11: 1/50 IPSI Belgrade Ltd. ARTSHOP GALLERY vm@ipsi.co.yu office@ipsi.co.yu .](https://reader035.fdocuments.net/reader035/viewer/2022070410/56649ea85503460f94bab6f4/html5/thumbnails/11.jpg)

Analysis and ImplementationAnalysis and Implementation
- Application is written in ASP.NET using C# as code-behind, and ADO.NET for database access.- Database server is SQL Server 2000.- Communication with the database is entirely made through XML (using SQLXML3.0 framework).
- Queries are made in XPath, while adding, changing and deleting of the records is done through UpdateGrams.
- Application is optimized for Internet Explorer 5.0 or higher, at the 1024x768 screen resolution. Netscape 7.0 or higher is also supported.
- 3D gallery is completely generated on the server side (dynamically) using VRML.

Track 1Track 1Interesting Details:Interesting Details:
• Native XML DBMS under development at IPSI Fraunhofer• Practical testing of the XML/XPath database access• Dynamic addition (to the system) of new multimedia types• 3D view of search results
![Page 18: 1/50 IPSI Belgrade Ltd. ARTSHOP GALLERY vm@ipsi.co.yu office@ipsi.co.yu .](https://reader035.fdocuments.net/reader035/viewer/2022070410/56649ea85503460f94bab6f4/html5/thumbnails/18.jpg)
1818/50/50
Track 1Track 1Interesting Details:Interesting Details:• Application that can connect on the fly to any DBMS which
supports XML/XPath is an interesting and possibly useful idea (user just has to set one XML file containing local field mapping, and one XSD to map the database fields to the pre-defined scheme)
• Cons:– XPath queries are lot less powerful then standard SQL queries– Inherently, loss of speed
(one complex SQL query had to be simulated with couple of XPath queries and additional processing in the code).
– For now, SQLXML3.0 does not support complete XPath standard.

Track 1Track 1Errors Made:Errors Made:
• Initially, content analysis, picture processing, and adding data to database were completely separated (as specified in the contract), with the idea of later (partial) integration.
• Turned out to be a bad idea(required a lot of interventionfrom the ArtShop system administrator when adding artworks).
![Page 20: 1/50 IPSI Belgrade Ltd. ARTSHOP GALLERY vm@ipsi.co.yu office@ipsi.co.yu .](https://reader035.fdocuments.net/reader035/viewer/2022070410/56649ea85503460f94bab6f4/html5/thumbnails/20.jpg)
2020/50/50
Track 1Track 1Lessons Learned:Lessons Learned:• Problem solved by complete integration of forementioned tasks
into the one system process which monitors input directory, automatically schedules picture processing and content analysis, and takes care of updating of all necessary fields in all required databases.
• With that, we achieved maximum automation, reduced time needed for artwork addition, and reduced amount of data transferred through the Internet (between the administrator’s machine and the application host).

Tools used in development:Tools used in development:• C# programming language – the chosen tool
– Advantage: Includes the best properties from other programming languages (C++, Java, Visual Basic)
– Disadvantage: slower processing speed than C++, which is not necessary in this application
• C++ - the best alternative tool
– Advantage: faster processing speed (unnecessary)
– Disadvantage: more complicated code, 50% of all bugs due to use of pointers

• If the new picture is smaller, every pixel is one pixel of the old picture.
• If the new picture is bigger, pixels are calculated based on the pixels surrounding the current.

Errors made:Errors made:
• Requests were not precise, so there was a gap at the end of the project between wanted and done
• Better results could be done with better using of ASP and XML

Lessons learned:Lessons learned:
• Every member of the team gets a part where his experience is dominating
• More planning at the start reduces a lot of work later
• Good communication between programmers can save a lot of time
